It will rotary cylinders. be understood that each of the walls 33d, 33g and Rotary cylinders, such as the shells of rotary 33h lie along radii of the ring. kilns, coolers, driers and grinding mills, are pro- As is indicated in Figure 2, the hook 33' at the vided with a plurality of riding rings which ropposite end of section 3! will be displaced and tate in fixed bearing elements to thereby roreversed with respect to the hook 33. Also, it tatably support the cylinders. It has heretowill be clear from Figure 3 that the hooks fore been the practice to form each riding ring at the ends of the section 32 are identical and of one piece of material and apply the rings by respectively complementary to the hooks on the sliding them endwise along the cylinders. As in section 3|. a result, initial application of a ring, as Well as The manner in which the hooks of the sections replacement, involves a considerable period of SI and 32 interengage will be clear from Figure time and labor. 3.

Referring to Figure 3, it will be noted that the I claim:

hook 33 comprises a shank 33a of less width than A rotary cylinder riding ring comprising a the body of section 3! and a head 33?). One side plurality of arcuate sections, the sections havwall of the shank and head is simply a continuaing their adjacent ends secured together by retion of the side wall 35 of section 31. The other spectively complementary hooks, each of said side wall 330 of the shank is at an obtuse angle hooks including a shank portion which is an exto the side wall 35 and its inner end joins wall tension of the ring section and a head at the outer 33d which extends at right angles to the side end of the shank, said head including a detent Walls of section 3!. The side Wall 33] of head 3 surface which lies at substantially a right angle lies Parallel 110 the Shank Wall 330 b s Offset with respect to the circumferential center line with respect to the latter wall so as to provide of the ring, securing means extending through a detent Surface 9/. The outer end wall 3% the engaged hooks in a direction transversely of 3 the ring, and annular retaining means adapted to be secured to the cylinder and abutting both side Walls of the ring so as to limit axial displacement of the ring with respect to the cylinder, the abutting surfaces of said retainer means and the ring side Walls being smooth and planar so as to allow the ring to rotate freely with respect to the cylinder.
